We study the regularity and the approximation of the solution of a parabolic evolution inequality in the framework of a Hilbert triple. We give a weak formulation which allows for data with weak regularity and we obtain new existence and regularity results. We also prove an optimal error estimate for the backward Euler discretization and we apply these results to the porous medium and the Stefan problem.

Abstract
We study the regularity and the approximation of the solution of a parabolic evolution inequality in the framework of a Hilbert triple. We give a weak formulation which allows for data with weak regularity and we obtain new existence and regularity results. We also prove an optimal error estimate for the backward Euler discretization and we apply these results to the porous medium and the Stefan problem.File in questo prodotto:
